基于智能疏浚模式的滨州港产能与控制模型

高效疏浚是疏浚施工一直追求的目标,也是研究的热点。基于智能疏浚模式的控制原理,对智能疏浚模式下"航浚6008"轮的滨州港工程施工数据进行分析,建立产能与控制模型,并对该耙吸挖泥船在滨州港工程的产能做进一步优化计算。结果表明,生产率受流量、浆体相对密度与泥泵特性等因素的影响和制约;疏浚过程中,智能疏浚模式主要依靠活动罩控制器与泥泵控制器的相互配合,当实际泥浆流速高于(最佳)设定值时,在其他边界条件不变时,活动罩自动控制器将活动罩下压,使耙头生产率与泥泵汽蚀控制相匹配;检测到泥泵汽蚀时,泥泵控制器通过降低泥泵转速而降低泥浆流速,以达到最佳混合物流速。

Capacity and control model of Binzhou Port based on intelligent dredging mode

Efficient dredging is not only the goal that has been pursued in the process of dredging construction,but also a hot spot in research. Based on the control principle of intelligent dredging mode,this paper analyzes the construction data of the Binzhou Port project under the intelligent dredging mode of "Hangjun6008"ship,establishes the capacity and control model,and further optimizes and calculates the capacity of this trailing suction hopper dredger in the Binzhou Port project. The results show that the productivity is affected and restricted by flow rate, slurry relative density, and pump characteristics. In the process of dredging, the intelligent dredging mode mainly depends on the cooperation between the AVC and the EPC. When the actual flow rate is higher than the( optimal) set value and other boundary conditions are invariant,the AVC will press down the visor to match the productivity of the drag head with the vacuum limit of the pump. When the pump limit reaches,the EPC reduces the flow rate by reducing the speed of the pump to achieve the optimal mixture speed.
